Y., a corporation of New York 2 Claims. (01.184-15) The present application is a division of my application, SerialNumber 162,099, filed January 19, 1927.

A further object is-to provide an automobile pit casing having trackwaysextending across the same, which casing may be removed and transportedto another location if desired, thereby obviating the loss of money nowentailed where concrete pits are used, and which concrete pits can notbe transported from place to place.

A further object is to provide an automobile pit casing without a bottomwhereby oils and greases will, when coming in contact with the bottom ofthe pit which is earth and cinders, soak into the ground, and anoperator in the pit will not slip as is the common diificulty with pitshaving concrete bottoms.

A further object is to provide the casing, adjacent its lower end, withtransversely disposed brace bars for preventing collapsing incident toearth pressure and uprights extending upwardly from the brace bars forsupporting the trackways which extend across the upper side of thecasing.

. preferably beneath the pit, and an adjustable drain member within thepit and provided with means whereby said drain member may be positionedbetween the trackways carried by the casing as desired.

A further object is to provide an automobile pit having a plurality oftrackways extending across the same with a drain tank having a drainagedevice which drainage device maybe shifted to various positions betweeneither or both 'of the trackways as desired.

With the above and other objects in view th invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a top plan view 'of oneof the pits.

Figure 2 is a front elevation of one of the pit casings.

Figure 3 is a vertical longitudinal sectional view through the pitcasing and pit taken on line 3'3 of Figure 1. A

Figure 4 is a vertical transverse sectional view taken on line 4--4 ofFigure l.

Figure 5 is an enlarged vertical transverse sectional view takenadjacent pit casings, showing the connections therebetween.

Figure 6 is a perspective view of one side of one of the pit casingswith the plate removed.

Figure 7 is an enlarged view in elevation of the drainage pipe, partsbeing shown in section to better illustrate the same.

Referring to the drawings, the numeral 1 designates the pit casing whichis preferably formed from sheet metal, and which casing is rectangularshaped, and is not provided with a bottom,- so when it is embedded in apit 2 in the ground 3, oil and grease will soak into the ground, therebyobviating one of the common difiiculties experienced in cement pits asat present constructed. Each casing 1 at its upper and lower side isprovided with rectangular shaped reinforcing frames 4 and 5, whichframes are connected together at the corners of the casing by means ofbars 6. Removably secured by means of bolts 7 to the sides of thecasings are plates 8, which are adapted to be removed when it is desiredto add additional pit sections as clearly shownin Figure 5, and at whichtime the sides of the frames 4 and 5 are connected together by means ofbolts 9 as clearly shown in Figure 5, therefore it will be seen that asthe business of a service station increases, it will only be necessaryfor the owner to add sections to his pits. By forming the easings fromsheet metal and from sections detachably connected, it is obvious thatif the owner abandons a particular station the pit may be divided intoits sections, removed from the ground and transported to a new location,which is not possible with pits as at present constructed of concrete,which cannot be transported, and must be destroyed or left, which is amaterial loss to the operator, when it is considered that in someservice stations there are as many as twenty or thirty of these pits,for instance those serving taxi cab companies. The lower rectangularshaped frame 5 is provided with transversely disposed brace bars 10,which brace the casing sections transversely and prevent collapseincident to pressure of dirt on the sides thereof. Brace bars 10 haveconnected thereto upwardly extending standards 11, which standards areconnected by means of angle members 12 to the undersides of thechanneled track members 13, which extend across the upper side of eachcasing. Each casing is provided with two pairs of trackways 13 forreceiving two machines at the same time, and at the same time theoperator will have access to the undersides of both machines withoutleaving the pit, and where a plurality of units are connected togetherwill have unobstructed access through the entire pit, which is not onlydesirable for eliminating the necessity of the operator coming out ofthe pit to go to another pit, but allows the operator to easily escapefrom the pit in case of fire, as it will only be necessary for theoperator to go into the adjacent casing and leave the pit by way of thesteps 14.

It will be noted that the trackways at the side of each casing extendbeyond the sides thereof substantially for half their width, thereforeit will be seen that when an adjacent section is desired, it will onlybe necessary to extend the sides of the adjacent section under thetrackways 13 referred to, and secure them in place by means of the bolts9 as clearly shown in Figure 5, and after which the deflecting flangesmay be connected. The adjacent flanges of the adjacent trackways 13 areconnected together by U-shaped upwardly extending flanges 15 as clearlyshown in Figures 1 and 2 and which flanges are sufficiently high toprevent an automobile from going over the same, consequently danger ofan automobile running into the pit is obviated. The U-shaped membercentrally of each casing is provided with arms 16, which extend entirelyacross the casing, thereby obviating any danger of lateral movement ofthe automobile on either of the trackways in one direction, and theouter flanges of the outer trackways are provided with similarlyconstructed flanges 17 for the same purpose. A removable platform 18 isprovided between the flanges 16 and onto which platform or walkway, theoperator of the automobile may have access to the machine or may use thesame when leaving the machine. Embedded in the ground, preferably belowthe pit and casing is a waste oil tank 19 from which a pipe 20 extendsupwardly substantially centrally of the chamber of the casing, andpivotally connected on the threaded upper end 21 of pipe 20 is ahorizontally disposed arm 22 having pivotally connected thereto by theunion 23 a second horizontally disposed pipe 24, which pipe 24terminates in a vertically movable pipe 25 in which is slidably mountedand vertically movable the tube 26 carried by a funnel 27. By providingthe pivoted pipe sections 22 and 24 it will be seen that the funnel 2'7may be positioned beneath either of the trackways as desired and wherethere are automobiles on both trackways, the operator may drain onemachine while working on the other. ,It will also be noted that byproviding the arms 22 and 24, the funnel may be placed in variouspositions beneath an automobile on either trackways, consequently thedevice may be easily and quickly adjusted to a position where 011 andgrease drained from the machine will pass through the piping to the tank19, from which it may be removed through a discharge pipe 28, forinstance by pumping, however a gravity drain maybe utilized if desired.The tubular member 26 has slidably mounted thereon a collar 29, which isprovided with. a set screw 30, and by loosening said set screw 30, it isobvious the operator can easily and quickly move the funnel 27 upwardlybetween either trackway 13 to a position adjacent the engine of anautomobile or any other part thereof, thereby obviating splashing ofgrease or oil drained from the machine. set screw 30 is tightened,thereby preventing downward movement of the tube 26, and causing thecollar 29 to hold the tube and the funnel against downward movement byengagement with the upper end of the pipe section 25.

From the above it will be seen that a service station pipe casing isprovided which may be easily and quickly removed from the ground andtransported to another location and that said casing is provided withmeans whereby additional casing sections may be added to opposite sidesthereof as desired.

The invention having been set forth what is claimed as new and usefulis:

1. An automobile pit casing comprising a casing, a plurality oftrackways extending across said casing, the outer trackways extendingbeyond opposite sides of the casing. and removable sides carried by saidcasing and forming means whereby additional casings may be attachedthereto.

2. An automobile pit casing formed from a plurality of casing sections,each casing section being detachably connected to the other sections,trackways extending across said casing sections, the outer trackways ofeach casing section over- After the adjusting operation the 1 lying theadjacent casing sections, the chambers.

of all of said casing sections being in communications with each other.

THOMAS MARTIN.
